In recent years, numbers of electronic devices rapidly grow in our surroundings. The demands and claims are changing with the increasing number of electronic devices. It placed emphasis on easier installation and management this devices. Simultaneously, it increases the requests to optimize power consumption and emphasis on the mobility, unification and advanced control and communication, which enables reciprocal communication among these devices. This paper describes a prototype of the universal gateway connecting various architecture of wireless sensor networks which are based on the architecture of intelligent sensors that use the open IEEE 1451 standard which provides the interface among sensors/actuators and instruments, microprocessors and networks.
